Lady Flo?

How did that happen? I'm not being nasty, but I can only remember her from Play School and Play Away. (Just looked her up on Wikipedia, she did a lot of stuff in the background, it sounds like it is deserved, but I can't say I remember her in any of the other roles mentioned.) Good for her.
Back on topic, I am watching his BAFTA speech, he is very interesting and a good speaker.
I can't judge on the British entertainment industry, but I can say, from looking at German TV, that it isn't a uniquely British problem. There are several ethnic actors here, but they get re-used a lot. That said, if you look at the dramas being made here in general, about 2 dozen actors seem to appear in 80% of productions, I'm not talking about ethics here, I mean all, including white Germans.
